Where have all the parks gone? Changes in Dublin's green space between 1990 and 2006

Between 1990 and 2006, the Dublin Region was amongst the most rapidly growing urban areas in Europe. The increase in population and industry presents particular challenges for spatial planning. The aim of the Urban Environment Project (UEP, www.uep.ie) is to provide spatial data and forecasts of future land-use patterns by using dynamic urban modelling which will underpin the development of decision-support tools for planners and policy-makers. For this study, we are using UEP landcover datasets to specifically address the question of what changes in urban green space (GS) occurred over a period of rapid growth (1990 – 2006). GS provides many functions within a city, ranging from the biotic (habitat provision, corridors of dispersal, reservoir populations) to the abiotic (storm water control, carbon sequestration, temperature regulation, increased property values). Over the study period (1990 – 2006) artificial urban surfaces have increased by 30% (by 8926 ha). Although the overall percentage of GS to built fabric stayed roughly constant over time (at about 23%), the losses and gains of GS were not evenly distributed throughout the city. GS was mainly lost near the city centre, where it converted to built areas. The GS gained was at the perimeter of the city to the detriment of agricultural land and semi-natural vegetation types. The result is a net loss of vegetated surfaces both within and outside the city. We discuss the possible implications of these changes in Dublin’s GS.

Simulating urban encroachment upon Natura2000 sites using the MOLAND model : supporting appropriate assessment
Brennan, Michael; Shahumyan, Harutyun; Convery, Sheila
The urban fabric of the Greater Dublin Area (GDA) has expanded rapidly over the past 20 years. This has lead to a decrease in environmental quality throughout the region and disturbance of protected areas. In an effort to guide development toward a more sustainable path in the region the “Strategic Planning Guidelines for the Greater Dublin Area” were introduced in 1999. These were updated in 2004 as the “Regional Planning Guidelines: Greater Dublin Area 2004-2016” and are currently in the process of another review to become the “Regional Planning Guidelines: Greater Dublin Area 2010-2022”. As part of the review an Appropriate Assessment was undertaken to evaluate the effect of
several potential settlement patterns on the region’s protected areas. The MOLAND model was used to simulate four scenarios of possible future settlement patterns for the GDA. These four scenarios were then evaluated in terms of the impact of development on protected areas within the region.

Air quality and MOLAND : description of a methodology to determine emissions output and affected populations
Casey, Edward; Twumasi, Bright Osei
In recent years, awareness of air quality issues in urban areas has increased significantly. The negative consequences
for human health as a result of poor air quality have resulted in numerous laws being enacted both in Ireland and
around the world, in an attempt to limit exposure. Within the urban environment, motor vehicles are one of the most significant contributors to pollution. As a result, constant monitoring takes place but little work is done on predicting likely changes in air quality, for better or worse, as a result of changes in landuse or transport. The MOLAND model can provide the basis for an emissions estimation methodology to predict changes in vehicular
emissions, and consequently air quality, both now and in the future, enabling policy makers and planners to examine the air quality implications of their decisions.

The urban fabric of the Greater Dublin Area (GDA) has expanded rapidly over the past 20 years. In an effort to coordinate development across the region the “Strategic Planning Guidelines for the Greater Dublin Area” were introduced in 1999. These were updated in 2004 as the “Regional Planning Guidelines: Greater Dublin Area 2004-2016” and are currently in the process of another review to become the “Regional Planning Guidelines: Greater Dublin Area 2010-2022”. As part of the review a Strategic Environmental Assessment (SEA) was undertaken to evaluate the effect of several future settlement patterns on the region’s environment. The MOLAND model was used to simulate four scenarios of possible future settlement patterns for the GDA. These four scenarios were then evaluated in terms of several indicators of sustainability and the results discussed in terms of the implications of these future settlement patterns on the environment of the region.

Analysing climate impact on energy demand using the MOLAND model
Liu, Xiaochen; Twumasi, Bright Osei
The importance and contribution of climate to energy demand are discussed. A linear regression model is developed to analyse future energy demand corresponding to climate change. The methodology for spatial analysis and integration to MOLAND are also provided in order to investigate possible consequences of different urban
development paths on energy consumption patterns.

Calculating population density for MOLAND in the Dublin urban area
Foley, Ronan; Critchley, Martin; Convery, Sheila
The EPA-funded Urban Environment Project seeks to apply MOLAND, a cellular automata based model, to predict a range of urban impacts in the Greater Dublin Region from 2006 onwards. One quantitative requirement,
at least in the input stages of model building, is to establish average population densities for the different residential land use classes because the population must be allocated to cells in these classes. It has a separate output function when actually used within the MOLAND model, relating to the estimation of numbers of people affected by a
particular scenario generated by the model. This working paper explores a series of approaches taken to identify population densities for a number of urban land-use categories. The results are documented against a number of differing spatial approaches to test for precision and applicability. Some suggestions are proposed as to the most effective method to use in developing the model.

Changing office location patterns and their importance in the perpheral expansion of the Dublin region 1960 - 2008
Attuyer, Katia; MacLaran, Andrew; Williams, Brendan
Recent development patterns have seen the urban region of Dublin evolve from a compact urban form towards a dispersed development pattern assisted by a shift in service-sector employment. In particular, this paper examines the movement of the office sector towards a number of suburban locations over the period from 1960 to 2008. It outlines the manner in which the geographic location of office development in Dublin has been transformed over recent years from one which focused primarily on a single dominant core from the 1960s until the 1980s, towards one in which numerous and widely-spread suburban sites tended to account for a growing proportion of new developments during the 1990s and early 2000s. The implications of this emerging pattern are of significant
importance to the long term development of the region.

Does MOLAND work as a tool for the assessment and/or as a predictor of the distribution of urban biodiversity in Dublin city?
Brennan, Michael; Twumasi, Bright Osei
The MOLAND project's aim is to provide spatial planning tools that can be used to assess, monitor and model the development of urban and regional environments. To date it has been applied to an area of over 70,000km2 across Europe. MOLAND's use as a tool for the assessment and forecasting of biodiversity is examined with Dublin city as a case study. It was found that, in its current form, the MOLAND model's use as a biodiversity assessment tool was limited. Several recommendations are made for improvements to its capability in this area.
